THE hazards of tobacco use are making headlines once again. Researchers at the prestigious Berkeley Lab presented a new global warning on the risks of third-hand smoke. The study published in the journal Mutagenesis confirms cancer-causing toxic tobacco residues can cause significant genetic damage in human cells.
The results of the study also confirm a harmful cumulative effect of the hazardous residues over time. Researchers found long-term exposure to third-hand smoke resulted in more DNA damage than short-term.
"Studies show that third-hand smoke clings to hair, skin, clothes, furniture, drapes, walls, bedding, carpets, dust, vehicles and other surfaces, even long after smoking has stopped," says Dr Lowell Dale.
Third-hand smoke is a relatively new concept and is characterized by the invisible residues left behind once second-hand smoke has disappeared. Third-hand smoke is thought to be particularly dangerous to infants and young children because they are more likely to inhale, ingest and touch surfaces containing the toxic residue.
